Hello, all.

Is it possible something has changed with the text file for problem Problem 42 (View Problem)? To clarify, 42 involves finding the number of so-called "triangle words" in a text file of common English words. I'm relatively confident in my algorithm (problem is pretty straight-forward), but I keep coming up with the same number, which comes back wrong. Also, the text file is reported to have nearly 2000 words, whereas the file I downloaded only had 1786. "Nearly 2000" seems a little generous, so I'm wondering if something has changed with the file. Believe me, I've tested a lot of other possibilities before questioning the text file.

Maybe I'm just screwed w/r to this one?

1786 is correct, as is the text file and the accepted answer

Dang.

Just figured it out. Cheers!

i keep getting 77 which is incorrect. Can someone let me know if this is close, so i can see if my algorithm is working at all.

@cdd
I would suggest that you scrap your existing algo and restart totally from scratch in a few days after you have forgotten how you tried to solve it in the first place.

Take a good look at the given example and make sure you understand it. Look at the word.txt file with Notepad or any other text editor and understand its structure so that you can parse it correctly with your algo.

thanks for the reply. Im pretty sure my algorithm is correct but could PM you my code for you to take a look at just to make sure?

nvm figured it out, i forgot that vectors start at the 0th index not 1.

Anybody doing this had ought to do problem 22 first. They are closely related.
